摘要

摘要: 脲酶诱导碳酸钙沉淀(EICP)是岩土工程领域一种绿色、环保的新型土体改良技术。与目前广泛关注的微生物诱导碳酸钙沉淀(MICP)相比,无需复杂的细菌培养流程,适用的土颗粒粒径范围更广,且在实际应用中避免了微生物生态安全等问题。通过对文献的归纳及整理,系统地阐述了EICP的固化机理、影响因素(脲酶性质、胶结液性质、固化方式、环境因素)等方面的前沿研究成果,分析了EICP技术发展中存在的问题及进一步的研究方向。

Abstract: Enzyme induced calcium carbonate precipitation (EICP) is a green and environment-friendly new soil improvement technology in geotechnical engineering. Compared with microbial induced calcium carbonate precipitation (MICP) which has been widely concerned at present, EICP is applicable to a wider range of sand particle sizes and does not need a complex sterile culture process, and the problem of microbial ecological safety is avoided in practical application. On the basis of literature induction and sorting, the research achievements on the cementitious mechanism of enzyme induced calcium carbonate precipitation and the influencing factors (enzyme properties, cementing fluid properties, curing methods, environmental factors) were systematically described. The existing problems and further research directions in development of the enzyme induced calcium carbonate precipitation technique were discussed.
